Micron MR6xx Receiver Programming - v1.1 ... v1.2

Micron MR6xx receivers implement a rich set of features with a common programming interface that allows functionality to be changed using most Micron model rail transmitters or a joystick Tx. Each row in the table below describes a 5 number sequence (levels 1 to 5) which is used to modify a feature's behaviour - e.g. change the ESC from centre-off to low-off throttle; set an auxiliary output as servo, on/off, or auto-direction light. Each row also contains a brief explanation of the function accessed by that row and a link to more detail in the features page.

Many table rows specify how a transmitter control is used to activate the receiver function; the row specifies (usually at level 4) a R/C channel. Transmitters encode each control (throttle, toggle switch, push button, etc.) as a number in the range 0..1024 and transmits them in the radio signal as separate R/C channels. The mapping between transmitter controls and R/C channels is described in the user manual for the transmitter. Throttle is usually channel 1, Selecta (if used) is channel 2, the bind button is channel 5, and so on.

Motor and servo outputs use the channel value directly to provide a proportional response to transmitter control changes. Switched outputs divide the R/C channel range into 2 or 3 positions: low, mid and high where low is a channel value less than 250, high is greater then 750 and mid is 511 +/- a small delta. The transmitter user manual describes the control positions corresponding to low, mid and high and the programming table shows how these low, mid and high values are used to switch the output.

For specific information on how to place a receiver into programming mode, see the receiver's user manual. See the transmitter's user manual or MR6xx Programming for information on how to use a transmitter for entering a program sequence.

Programming Table

Menu	Level 2	Level 3	Level 4	Level 5	Information

1 = ESC Configuration	1 = ESC Num	1 = Centre off (1 ch: fwd/rev) esc-centre-off	Throttle 1-10 = R/C Channel		Forward and reverse with one control, off at control centre (-100% .. 0 .. +100%) prog: 1,1,1,1 = Menu1, H1, centre-off, R/C chan 1
1	1 = ESC Num	2 = Low off (2 ch: speed & direction) esc-low-off	Throttle R/C Channel 1-10 = R/C Channel	Direction 1-10 = R/C Channel	One control for throttle (0 .. 100%) Second control for direction (prog: 1,1,2,1,3 = Menu1, H1, low-off, R/C chan 1, R/C chan 3
1	1 = ESC Num	3 = Not used
1	1 = ESC Num	4 = Motor start power min-power	0-10 = Tens (x10) (0-flash = 0)	0-9 = Units (x1) (0-flash = 0)	Minimum power level, the motor will jump to this power when the throttle is opened. (0% for full power range) (eg: 1,1,4,2,5 = Menu1, H1, min power, 25%)
1	1 = ESC Num	5 = Motor max power max-power	0-10 = Tens (x10) (0-flash = 0)	0-9 = Units (x1) (0-flash = 0)	Maximum power level (100% for full power range) (eg: 1,1,4,8,0 = Menu1, H1, max power, 80%)
1	1 = ESC Num	6 = Motor reverse reverse	1 = Normal 2 = Reversed		Reverse motor rotation
1	1 = ESC Num	7 = ESC PWM pwm	1 = 16kHz* 2 = 8kHz 3 = 4kHz 4 = 2kHz 5 = 1kHz 6 = 500Hz 7 = 250Hz 8 = 120Hz		Set the speed controller PWM frequency, the default setting is 16kHz. Lower PWM values give increased slow speed torque at the expense of motor heating
1	1 = ESC Num	8 = Motor soft start/stop - inertia soft-start	Acceleration 1 = immediate 2 = 0.25s 3 = 0.5s 4 = 1s 5 = 2s 6 = 4s 7 = 8s	Deceleration 1 = same as accel 2 = 0.25s 3 = 0.5s 4 = 1s 5 = 2s 6 = 4s 7 = 8s	Set the rate of throttle change - acceleration and deceleration, which can be set independently or the same. The times are for full range, 0..100% throttle. 1,1,8,1,1 = no inertia, motor speed immediately follows the throttle control 1,1,8,4,1 = accel and decel over 1s The default is immediate; 0.25s or 0.5s will reduce ESC heating for motors with significant BEMF.

2 = Servo Configuration	1-6 = P1-P6	1 = Normal Servo servo	1-10 = R/C Channel	1 = normal speed 2-6 = slow motion	Servo PPM signal on any 'P' pad. Default is full throw from full stick movement; servo travel and reversing can be adjusted using level3 = 7. Slow motion times are roughly equal to the number of seconds for end to end rotation (for an 'average' servo).
2	1-6 = P1-P6	2 = Not used			Placeholder for offset servo
2	1-6 = P1-P6	3 = Not used			Placeholder for toggled servo

(eg: 3,4,2,5,1 = P4, Start off, toggle when Ch5 is low) (eg: 3,6,2,5,2 = P6, Start off, toggle when Ch5 is high)
3	1-6 = P1-P6 7-10 = F1-F4 (A-D)	3 = Dual Action Latching latch2	1-10 = R/C Channel	Channel high 1 = >2s toggle 2 = <1s toggle Channel low 3 = >2s toggle 4 = <1s toggle	1 R/C channel can control 1 to 4 outputs.

4	4 = Failsafe / Cruise Failsafe	Time to stop after signal loss: 1-4 = 1-4s 5 = sleep time			Time to kill outputs after signal loss. Use 'Sleep time' (level 3 option 5) for 'cruise control' with transmitter switched off.
4	5 = Emergency stop EStop	1 = Disabled			Manual trigger stop over radio (eg: 7,5,2,3,6 enabled using Ch3 low with 6s delay - i.e. Ch3 must be low for at least 6s to trigger.)

4	9 = Deselect Action Selecta	1 = stop 2 = continue			Action when deselected: 'continue' or 'stop': continue - ESC continues at the last throttle setting. stop - throttle smoothly closes the default is 'continue'.
4	10 = Auto-light control auto-lights	1 = Disabled			Enable/disable the auto-direction outputs using an R/C channel. When this control is enabled, the initial state of auto-lights is disabled (i.e. off). Any other function mapping of the R/C channel remains - e.g. output on/off switching.

4	14 = Show Firmware Version Version				Show the firmware version by flashing the LED (and LED2 if enabled). Firmware versions are 2 numbers: major and minor (e.g. 1.2). 0.5s of rapid flashing is shown first, followed by a flash count for the major number, a pause and then a flash count for the minor number. A zero is shown as a very brief flash, much shorter than the normal flash. The pattern is repeated until the receiver is switched off.

5 = Radio Configuration	1 = Binding Bind	1 = DSM2/DSMX Protocol	1 = auto 2 = manual		Choose auto or manual bind. The pins/pads for manual bind are specified in the receiver manual.
